Abstract

This study was conducted to examine the effect of soy flour on tapioca non- steamed fermentation. A whole soy flour was higher than roasting soy flour in alcohol content. Alcohol content was increased up to 2% of soy flour, and decreased after adding 3% soy flour. The pH and total acidity were showed no significant differences by adding soy flour, roasted soy flour, water and enzyme. The optimum conditions for alcohol production were 2% (w/w) of soy flour,0.5% (w/w) of enzyme and 250% (v/w) of water at 96 hr. Addition of soy flour increased yield of alcohol.

콩분말을 질소원으로 첨가하여 타피오카의 무증자 알콜발효에 미치는 영향을 조사하였다. 생콩분말 첨가가 볶음콩분말 첨가 보다 알콜함량이 전반적으로 높게 나타났으며, 콩분말 농도별 첨가에 따른 영향은 생콩분말 첨가의 경우 2%까지는 증가하다가 3% 이후로 감소하는 경향을 나타내었으며, 볶음콩 분말의 경우 첨가농도에 따른 알콜함량은 큰 차이를 나타내지 않았다. pH와 총산은 생콩분말 ,볶음콩분말의 첨가, 가수량과 효소제 첨가에 따른 영향을 거의 받지 않는 것으로 나타났다. 생콩분말 2%(w/w), 가수량 250%(v/w), 효소제 0.5%(w/w)를 사용하여 3$0^{\circ}C$, 96시간 발효하였을 때 알콜 함량이 가장 높은 것으로 나타나 콩분말을 이용하여 타피오카의 무증자 알콜발효 조건을 설정 할 수 있었다. 콩분말 첨가는 타피오카의 무증자 알콜발효에서 알콜수율을 증가시켰다.
